Press Y key and Enter key. The node will reboot.

Scripts to install AOS and/or configure Hypervisor are executed at the initial boot.
It may take up to an hour for the installation to complete.

The node may reboot a few times automatically during the installation.
Do not shut down and/or restart the host OS (AHV/ESXi/HYPER-V) by user operation until the installation is completed.
If it is shut down manually during operation, the script may stop and the initial configuration may fail.

The installation is considered complete when the following conditions are reached.

・AHV
Log in to the AHV host as a root user. The password is nutanix/4u.
Confirm the network interface "br0" exists by executing the command.
(It obtains IP address if the node is connected to the network that is enabled DHCP.)
　# ifconfig -a br0

・ESXi
The connection address is "http://NTNX-ServiceTAG-A/" and the management IP address is obtained by DHCP.
(If not connected to the network, a message appears indicating that DHCP has failed to obtain a management IP address.)
